Fermentation Questions With Complete Solutions
A molecule becomes more oxidized when it __________.
Correct Answers Loses and electron
A small amount of ATP is made in glycolysis by which process?
Correct Answers Transfer of a phosphate group from a
fragment of glucose to ADP by substrate-level phosphorylation
After completion of the citric acid cycle, most of the usable
energy from the original glucose molecule is in the form of
__________. Correct Answers NADH
All of the processes involved in cellular respiration produce
ATP. Which process produces the most ATP? Correct Answers
Oxidative phosphorylation
Cells must regulate their metabolic pathways so that they do not
waste resources. What is the most common mechanism that
regulates cellular respiration in most cells? Correct Answers
Feedback inhibition of glycolysis
During aerobic respiration, molecular oxygen (O2) is used for
which of the following purposes? Correct Answers At the end
of the electron transport chain to accept electrons and form H2O
During the energy investment phase of glycolysis, __________.
Correct Answers Glucose is phosphorylated before it is split
into two three-carbon molecules
, During the energy payoff phase of glycolysis, __________.
Correct Answers NADH and ATP are produced
Fermentation by itself produces no ATP but keeps glycolysis
going, which produces a small amount of ATP. How does
fermentation do this? Correct Answers Fermentation oxidizes
NADH to NAD+, which facilitates the production of ATP in
glycolysis.
Fermentation is essentially glycolysis plus an extra step in which
pyruvate is reduced to form lactate or alcohol and carbon
dioxide. This last step __________. Correct Answers Enables
the cell to recycle the reduced NADH to oxidized NAD+
Glucose is the primary fuel for cellular respiration. Which of the
following molecules can also be used by cellular respiration to
generate ATP?
A. Glycerol
B. Fatty acids
C. Amino acids
D. All the above. Correct Answers D. All the above.
In preparing pyruvate to enter the citric acid cycle, what is the
correct steps that occur? Correct Answers Pyruvate is oxidized
and decarboxylated, and the removed electrons are used to
reduce an NAD+ to an NADH.
In the overall process of glycolysis and cellular respiration,
__________ is oxidized and __________ is reduced. Correct
Answers Glucose: oxygen
